Using Zen Cart for entries to an event?

I'm looking for a shopping cart for our running club to use for entries to a fun run/walk event we are shortly going to hold, plus to allow members to pay club subscriptions on line.

As far as I can tell, the two non-standard features we need are:

• the ability for people to enter (purchase) without setting up an account, and

• to allow additional informational information to be entered depending on the 'product' purchased and the number of them.

For example, if someone pays for multiple entries to the event with one payment; each entry will need name, ######, DOB etc. Likewise if the product is a family club subscription we need to be able to enter the details of each family member.

I understand there is a checkout without account module to do the first. Can Zen do the second?
